First database 13 and the second database 14 may each be database server, but the two can select different type Database server, in this application, first database 13 is mainly used to store unclosed orchestration instance data, Redis database can be selected.Second database 14 can be used to back up all flow instance data, can store all tied The flow instance data of beam, can select MySQL database server, but be not limited to this relevant database.

It can be seen that its all corresponding flow instance data can store to first database during service operation 13, in the case where the service ending, all flow instance data of the business stored at this time can be synchronized to the second number According to library 14, later, the flow instance data for the business that first database 13 stores is removed, reduce the memory to first database The occupancy in space guarantees the normal use of other business services.

Classification storage mode based on the flow instance data that the application proposes, for the flow instance number being over According to can directly be read from the second database 14, which reduces the access request numbers to first database, improve Write the availability of service.Thus, the application is by this classification storage mode, and realize the storage of first database data can Retractility externally provides high concurrent interactive interface while guaranteeing data consistency.

Optionally, as shown in Fig. 2, the above-mentioned first database of the application and the second database can use master slave mode, Realize the storage to orchestration instance data, specific implementation process the application is not described further, and is not limited to shown in Fig. 2 Two groups of master-slave databases.

It is only to realize that the application provides for the system structure of three-layer network shown in Fig. 2 deployment in addition, it is necessary to illustrate Business flow processing method system architecture example, it is not limited to this structure shown in Fig. 2 is also not limited to each Two groups of servers that layer provides, can be adjusted flexibly the quantity of each stratum server, the application is no longer according to actual development demand Enumerate detailed description.

The system structure in conjunction with shown in figure 2 above and 3, in order to better understand workflow engine under concrete application scene The course of work, below by being illustrated on the whole from business processing flow, referring to a kind of industry provided by the present application shown in Fig. 4 The signaling process schematic diagram of one embodiment of processing method of being engaged in, this method can be applied to service side, as shown in figure 4, this method It may include but be not limited to following steps:

Step S101, client initiate acquisition of credentials request to the Verification System of application server；

In the present embodiment, the user rs credentials that Verification System can be the logical process layer deployment of application server are issued The heart can be used to provide the voucher ticket for showing user identity for user, and guarantee that the user is able to access that in system The access credentials of application.In this way, user client can carry voucher access other application, so that other application can be based on The voucher identifies user identity, and then determines whether the user is allowed access to apply.

Wherein, acquisition of credentials request usually may include the log-on message of user's input, so that user is accordingly to user's Identity is verified, and the content that the application includes to the log-on message is not construed as limiting, such as user identity ID, user images, Can requirement according to Verification System to user identity authentication determine.

Step S102, Verification System respond acquisition of credentials request, distribute corresponding identity documents for client user；

The identity documents are fed back to client by step S103, Verification System；

After analysis above, after Verification System receives acquisition of credentials request, can to it includes log-on message test Card determines that the user for initiating acquisition of credentials request by client has access authority, i.e. it can be the use that log-on message is qualified Unique identities voucher ticket is distributed at family, and is fed back to client, and the application is distributed how Verification System is each user The method of identity documents ticket is not construed as limiting.

Optionally, above-mentioned identity documents ticket may include SHA1 (Secure Hash Algorithm, secure Hash Algorithm) information such as signature algorithm TOKEN (interim token), the symmetrical encryption and decryption aes algorithm key of message, authority expired time.

Step S104, client utilize the identity information, generate business request information；

In the present embodiment, in the case where user needs to obtain certain message of certain orchestration instance, user is used It, can be according to the identity documents, the head of the customized request after client obtains the identity documents of the user from Verification System Field, such as user's unique identifier, request message SHA1 signature.Later, the message that can use in identity documents symmetrically adds Aes algorithm key is decrypted, request message is encrypted, recycles encrypted request message, generates business request information, is protected The safety of the service request of external transmission is demonstrate,proved, specific ciphering process the application is not detailed.

Optionally, under different application scene, the type of message for the business request information that the present embodiment generates may include: Initiate message, submit pending message, termination process message, REFER messages, the pending message of countersign, rejection message etc., based on difference The message of type will generate the service request of respective type, but be not limited to these types of type enumerated herein.

The system architecture in conjunction with shown in figure 2 above, the application can show that workflow is drawn in the display interface of client-side The message interface list of offer called is held up, user can therefrom select message required for this initiation operation flow to connect Mouthful, with by calling the message interface, the corresponding business request information of generation is simultaneously sent to workflow engine.As user needs A hiring process is initiated, can choose the message interface for initiating this type of message of message, realizes the calling to the message interface, Inform that workflow engine user current business demand, specific implementation process the application are not construed as limiting.

As it can be seen that the present embodiment operation system initiates phase by the way of calling the message interface of offer of workflow engine The business request information answered makes it only need to pay close attention to own service, without paying close attention to the circulation logic of operation flow, but by working It flows engine and is based on the business request information, execute corresponding service logic, thus, workflow engine provided by the present application is by industry Business workflow is separated with business logic processing, so that business flow processing is more clear, it is real convenient for tracing and positioning operation flow Abnormal nodes in example.

And the application uses HTTP API interactive mode, simplifies the access of operation system, reduces learning cost.

The business request information is sent to workflow engine by step S105, client；

Step S106, workflow engine obtain the identity documents of the user from Verification System；

Step S107, workflow engine utilize the identity documents, carry out validity check to business request information；

Step S108, workflow engine is in the case where verification passes through, and according to the identity documents, obtains the service request and disappears The message content of breath；

In the present embodiment, after workflow engine receives the business request information of user's transmission, the business can be first verified Whether the validity of request message, that is, the user for initiating the business request information have lawful authority, so, workflow engine can To obtain the identity documents of the user from Verification System, and then the business request information is carried out effectively using the identity documents Property verification, specific checking procedure the present embodiment is not detailed.

By above-mentioned verification, in the case where verification passes through, the key in the identity documents of acquisition is recycled, business is asked It asks the message content of message to be decrypted, obtains the requested message content of user, the decrypting process and above-mentioned ciphering process pair It answers, the present embodiment is not described further.

Step S109, workflow engine obtain with the matched orchestration instance of the message content, and by the operation flow The instance data of example is stored to Redis database；

Step S110, workflow engine handle the orchestration instance, update the example state of respective nodes；

Step S111, workflow engine feed back to the instance data of updated example state and orchestration instance Client.

It should be understood that requesting the business of operation for user, orchestration instance is simultaneously not finished, therefore, obtain with After the orchestration instance that the message content of Client-initiated business request information matches, i.e. workflow engine response business is asked Message is sought, it, can be (i.e. above-mentioned to Redis database by example data buffer storage after obtaining the orchestration instance of this request First database in system architecture), specific storage mode is without limitation.

It optionally, can be by the example ID of each orchestration instance for the key value database of this type of Redis database (i.e. the unique identification of the orchestration instance) is used as key key, and its corresponding instance data (can be the number of JSON format According to) value value as the key, realize the storage to the instance data of different business flow instance.Therefore, when needing to obtain When the instance data of certain orchestration instance, the example ID of the orchestration instance can be directly utilized, inquiry obtains corresponding Instance data.

Wherein, it for the orchestration instance of the application, is usually generated for the operation flow definition figure that user provides , and the operation flow is defined figure and can be configured accordingly using JSON protocol definition, and for different operation flow definition Flow definition ID, to distinguish each operation flow definition figure, the application is not detailed the process that operation flow defines.The application is real In the application of border, for different types of business request information, the process that workflow engine obtains corresponding service process example may It is different.Assuming that the business request information is to initiate message, hiring process is such as initiated, workflow engine can be fixed according to operation flow Justice figure, initializes orchestration instance context class, obtains hiring process example, meanwhile, the application can be by this trick of initiation The instance data of flow instance is engaged to be cached in Redis database.

Later, in the implementation procedure of hiring process, the instance number of the hiring process can be read from Redis database According to, and apply it in specific recruitment, that is, the instance data is utilized, it is corresponding to execute each node in hiring process example Service, and the example state of respective nodes is updated, so that recruitment person can learn the newest shape of each node of hiring process in time State learns what node for being currently at hiring process, meanwhile, guarantee that the Redis database can store and each is existed by recruitment person State in hiring process.

Optionally, for Client-initiated business request information, as described above, it can also be other kinds of and disappear Breath, such as all kinds of business request informations in operation flow implementation procedure listed above, in this case, workflow engine can be with The example ID of orchestration instance according to the business instantiates example context class and Redis flow instance class, obtains business Currently processed node in process by the polymorphic mechanism of interface, realizes orchestration instance number using different type node later According to update and the update of each node instance state, and updated instance data is encrypted, by encrypted instance number Accordingly and updated example state feeds back to client, to meet the business demand of Client-initiated business request information.

Wherein, in the operational process of orchestration instance, generated updated instance data, can cache to In Redis database (first database i.e. in above system structure), realize to being generated in orchestration instance implementation procedure Data persistent storage.And in the case that example state in the updated shows that orchestration instance terminates, the application can The instance data of the orchestration instance in Redis database at this time is synchronized to MySQL database (i.e. above system structure In the second database) storage, while the instance data of the Redis database caches can be deleted, reserve memory space Continue to cache the instance data of other orchestration instances.

Description based on foregoing embodiments, referring to Fig. 5, is that the application is real in conjunction with figure 2 above and system architecture shown in Fig. 3 The flow diagram of another business flow processing method of example offer is applied, this method may include:

Step S201 detects the example state of each node in orchestration instance；

Step S202 verifies whether the orchestration instance terminates according to the example state, if not, entering step S203；If so, executing step S204；

Step S203 caches the instance data of the orchestration instance to first database；

Such as above-mentioned analysis, first database can be Redis database, and orchestration instance is not finished, and illustrates the business The corresponding service of at least one node of flow instance has not been executed, i.e., services in the presence of at least one node is corresponding wait hold Row.

Optionally, the Redis database of the application can be realized real using such as Hash, Lish, String data structure The storage of number of cases evidence, and guarantee the consistency of data while improving performance by affairs.Since Redis database belongs to Key value database, so, in the related data of storage service process, as operation flow defines information, each operation flow reality The instance data etc. of example, can be set corresponding unique identification as key key, and deposit using corresponding data as value Storage.

Specifically, can be generated globally unique by flow definition ID, example ID, pending ID etc. by specifying step-length mode Major key, that is, be used to inquire the unique identification of corresponding data, but is not limited to a kind of this mark generating mode, with Hash data knot For structure, the data of Redis database purchase mainly may include operation flow definition, orchestration instance, instant node, to It does that task, processing people be pending and the hash value of the storage objects such as personal pending center, and can have between these storage objects Just like storage relation schematic diagram shown in Fig. 7.

The instance data of the orchestration instance of first database caching is synchronized to the second database by step S203, And delete the instance data of the orchestration instance of first database caching.

Wherein, the second database can be Mysql database, and however, it is not limited to this.

To sum up, the instance data that first database caches unclosed orchestration instance can be used in the present embodiment, makes With the instance data for the orchestration instance that the second database purchase has terminated, by this timing by process in first database The instance data of end is synchronized to the mode of the second database, realizes the dynamic retractility of memory headroom, avoids all examples Data are all buffered in first database, occupy the memory space of first database, influence the normal work of other orchestration instances Make；Meanwhile the orchestration instance for being over, when needing to consult example data, directly to the second database into Row read operation reduces the access times to first database, improves the availability for the service of writing；Moreover, because of first The high concurrent processing capacity of database ensure that while the application realizes the instance data high concurrent of orchestration instance The consistency of data.

Below in conjunction with concrete application scene, the method for processing business of the above embodiments of the present application description is illustrated, Operation flow as shown in connection with fig. 7 defines figure, which can be the flow definition of user determine according to actual needs, But it is not limited to operation flow definition figure shown in Fig. 7 in practical application, an example is only used as to be illustrated.Assuming that user Currently processed node under the application scenarios is " examination & approval 1 ", and currently processed people is A, and the method for processing business accordingly executed is such as Shown in Fig. 8:

Step S301, client submit pending message to workflow engine；

It should be understood that the processing people that step S301 can actually be currently processed node submitted by client it is pending Message, the present embodiment is only illustrated by taking this type of message of pending message as an example, for other kinds of business request information Method for processing business it is similar, the application does not do and is described in detail one by one.

Step S302, workflow engine instantiate flow instance or more according to the flow instance mark in the pending message Literary class and flow instance class；

In the present embodiment, for different orchestration instances, it is commonly configured with unique flow instance mark, such as above The example ID of the orchestration instance of description, the application to the configuration method of the example ID without limitation, can using Redis from Increase key mode to generate, also can use SnowFlake algorithm (i.e. a kind of distribution ID generating algorithm) generation etc..

It circulates control class figure referring to operation flow shown in Fig. 9, the application can use that business request information is for example above-mentioned to be mentioned Explain the example ID done in message SubmitMsg, instantiate Process Instance Context class (FlowInstanceContext class) and Orchestration instance class (FlowRedisContext class).

Wherein, after receiving message about workflow engine, validity check and message content encryption process, Ke Yican According to the description of above-described embodiment, this will not be repeated here for the present embodiment.

Step S303, workflow engine determine that currently processed node is pending type node, obtain pending type node class；

Step S304, workflow engine instantiates the pending type node class, and stores currently processed node Approval results state；

It is determining that currently processed node is " examination & approval 1 ", is being pending type node, corresponding TaskNode class (i.e. pending class Type node class), workflow engine can instantiate the TaskNode class, execute Execute method and store the currently processed node Approval results state, specific implementation process the present embodiment be not described further.Step S305, workflow engine obtain next stage and execute Node；

The present embodiment can be by executing ChangeFlowState () method, and the next stage for obtaining currently processed node is held Row node, such as " branch 1 " in Fig. 7.

Step S306, workflow engine determine the next stage execute node be branch pattern node, return step S305 after It is continuous to execute, until it is pending type node that acquired next stage, which executes node, the next stage of the pending type is executed into node It is updated to currently processed node；

In this application, the gateway type node in orchestration instance may include branch pattern node ForkNode, Conutersign type node JoinNode and exclusive or type node XorNode, wherein exclusive or type node, that is, exclusive or node is in Business Stream During Cheng Liuzhuan, automatic submission strategy is generallyd use, that is, is defaulted as processed state, processing result is that examination & approval pass through.Except this Before, the instant node in orchestration instance can also include start node StartNode, task node TaskNode, knot Shu Jiedian EndNode etc. is specifically referred to operation flow as shown in Figure 7 and defines all types of nodes in figure.

In the orchestration instance that operation flow as shown in Figure 7 defines that figure obtains, determine that currently processed node is " to examine 1 " is criticized, it is " branch 1 " that next stage, which executes node, is gateway type node, specially branch pattern node, can touch automatically The ChangeFlowState () method of hair obtains next stage and executes node, and " branch 2 " is arrived in circulation, similarly continues automatic flow and arrives Its next stage executes node " examination & approval 2 " and " examination & approval 3 " i.e. pending type node；It is " branch 1 " in currently processed node updates In the case of, automatic flow to next stage execute node be also possible to be " branch 3 ", also automatic flow is held to its next stage at this time Row node " examination & approval 4 " and " examination & approval 5 ", i.e., pending type node.

Step S307, workflow engine update the example state of the currently processed node；

The updated example state of flow instance interior joint is fed back to client by step S308, workflow engine.

Specifically, the present embodiment can be called in the case where determining currently processed node is pending type node The pending state of ChangeFlowState () instantiated nodes, i.e. update example state, determine that currently performed operation flow is real The node of example is examination & approval 2, examination & approval 3, examination & approval 4 and examination & approval 5, while can also obtain the corresponding processing people of each pending node, later, Updated example state is fed back into client, updates the state of each node in the operation flow that client is shown, to remind The processing people of each pending node is handled in time, the application to the renewal process of operation flow without limitation.

In addition, in conjunction with the description of above-described embodiment, in such as above-mentioned operation flow implementation procedure, for orchestration instance Unclosed instance data can continue caching to Redis database, according to sequence (i.e. business of operation flow after update Flow instance interior joint executes sequence) the corresponding service of node, while the type according to performed node are executed, it updates in fact Example state and instance data, however, it is determined that the operation flow terminates, can be by the orchestration instance of Redis database caches Instance data is synchronized to MySQL database storage, while deleting the instance data of Redis database caches.Wherein, about industry Each node corresponding with service executes sequence in business process, will be according to user's operation flow definition figure determination predetermined, not It is confined to operation flow definition figure shown in Fig. 7.

Based on above-mentioned design, in the application practical application, for the operation flow of the definition under different scenes, can adopt With corresponding instant node processing strategie (it can be a kind of data processing algorithm), the instance data of the operation flow is obtained, Wherein, which may include closest branch node matching strategy CBNM, based on DFSP (Depth First Search Path) internode path traversal strategies, reject strategy, XOR exclusive or circulation strategy, can terminate strategy, Join countersign The combination of one or more of strategies such as circulation strategy, can select according to practical process demand, will enumerate several answer below With in the business flow processing of scene, the realization of service logic circulation process is illustrated, but is not limited to the application and is enumerated Several application scenarios service logic circulation.

In practical applications, after the currently processed node for executing orchestration instance, whether can circulate to next Grade executes node, as shown in fig. 7, whether can circulate if currently processed node is " countersign 2 " node to " examination & approval 6 " node, Whether the node in all paths before needing to check " countersign 2 " matched branch node of node, which is carried out, finishes, such as Fruit is that just will continue to circulation to " examination & approval 6 " node, otherwise, the pending corresponding service of node not yet terminated such as needs.Thus As it can be seen that generally requiring to search currently processed node (referred to herein as countersign node or exclusive or in orchestration instance implementation procedure Node) closest branch node and currently processed node and its closest branch node between all paths etc..

Based on this, operation flow as shown in connection with fig. 7 is defined figure by the application, to the reality for how searching closest branch node Existing method is illustrated, specifically with " when business process flow goes to " countersign 1 " node, return branch node " branch 2 "；Work as industry When being engaged in workflow to " countersign 2 " node, return branch node is " branch 1 ", rather than return branch 2 or branch 3 " this answer For scene.

When regulation due to branch node with countersign node, branch node and exclusive or node in flow definition must go out in pairs It is existing, so, it needs to be determined that the present embodiment can under the scene of the closest branch node to match with countersign node or exclusive or node To select CBNM strategy to realize, specific implementation process is referred to flow diagram shown in Figure 10, simultaneously for this application scenarios It is not limited to the business flow processing method that the present embodiment provides, as shown in Figure 10, the present embodiment is answered mainly for realization is above-mentioned It is illustrated with the realization process of scene, the closest branch section of currently processed node is obtained using node matching strategy CBNM Point, the specific implementation process is as follows:

The currently processed node of orchestration instance is inserted into storehouse by step S401；

Stack is a kind of linear list that operation is limited, and only in one end of table, fortune is inserted into and is deleted to (i.e. stack top) for limitation It calculates, step S401 is actually that currently processed node pushes on step.In the present embodiment, such as problem above is described, currently processed Node can be the countersign in user-defined orchestration instance as shown in Figure 1 or the node of exclusive or type, i.e. " countersign 1 " Node, " countersign 2 " node.

Step S402 obtains the preposition node set of currently processed node according to orchestration instance；

In the present embodiment, preposition node set can be the gateway type node in orchestration instance, such as point in Fig. 7 Zhi Jiedian, countersign node, exclusive or node etc..

Step S403, selecting any preposition node in the preposition node set is node undetermined；

Step S404 detects whether the node undetermined is branch pattern node, if so, entering step S405；If not, Execute step S407；Step S405 deletes currently processed node from storehouse；

Step S406, whether detection current stack is empty stack, if not, return step S402；If so, returning to section undetermined Point；

Step S407 detects whether the node undetermined is countersign or exclusive or type node, if not, return step S402； If so, entering step S408；

The node undetermined is inserted into storehouse, and return step S402 by step S408.

As it can be seen that, if currently processed node is " countersign 1 " node, matched preposition node is point in the present embodiment Branch type node will return to branch node execution according to the above-mentioned steps that the present embodiment describes；If currently processed node is " countersign 2 ", there is countersign node and exclusive or node in preposition node, that is to say, that preposition node of the circulation to " countersign 2 " node There are " countersign 1 " node and " exclusive or 1 " node, in the manner described above, can determine nearest point that the two nodes match respectively Zhi Jiedian is " branch 2 " node and " branch 3 " node, may further determine the closest branch section that " countersign 2 " node matches Point should be " branch 1 " node, so, when business process flow goes to " countersign 2 " node, its closest branch section can be returned Point, i.e. return " branch 1 " node, so as to all paths inquired between " branch 1 " node and " countersign 2 " node.

It is to be appreciated that about the reality for conutersigning the respective closest branch node of node and exclusive or node in inquiry business flow instance Existing method, it is not limited to the method for the present embodiment description.

Application scenarios are described in conjunction with above-described embodiment, the application can be using the internode path traversal based on DFSP algorithm Strategy, to obtain the road between countersign node (or exclusive or node) and its closest branch node (branch node to match) Diameter is still illustrated so that operation flow shown in Fig. 7 defines figure as an example, referring to Fig.1 flow diagram shown in 1, is obtained different The process in the path between type node may include but be not limited to following steps:

Step S501 obtains operation flow description information, determines the branch node in the operation flow description information, and will The branch node is inserted into storehouse；

Step S502 obtains not visited node set after the stack top node of the current storehouse；

If the node after stack top node there are not visited node, illustrates to deposit between the branch node and countersign node It is not queried at least one path；Conversely, all paths between two nodes that explanation inquires.

Step S503, the next stage for detecting the branch node execute whether node is countersign in operation flow description information Node, if not, entering step S504；If it is；Enter step S505；

The next stage is executed node and is inserted into storehouse, return step S501, until storehouse is empty stack by step S504；

Step S505 obtains the path between the branch node and the countersign node, and exports the path of acquisition.

By taking all paths between acquisition " branch 1 " node and " countersign 2 " node as an example, 1 node of branch is pushed on, if stack There are the node set of not visited mistake after top node, the next stage for detecting 1 node of branch executes whether node is countersign 2 Node, if so, 1 node of branch is obtained to the path of 2 node of countersign, if not, next stage execution node is pushed on, Continuing to test stack top node in the manner described above, there are not visited node sets later, and its its next stage is executed node It whether is " countersign 2 ", until obtaining branch 1 and conutersigning all paths between 2 nodes, i.e., currently processed node is not interviewed The next stage asked executes node.

It is to be appreciated that about the path query method between different type node, it is not limited to the present embodiment description The above method, can also use other depth optimization algorithms, and the application is no longer described in detail one by one.

In operation flow, it will usually encounter the circulation feelings rejected from currently processed node to a certain execution node before Condition just needs to be implemented reject strategy to realize that this operation flow circulates, specifically with " current pending node is rejected to front at this time Be illustrated for this application scenarios of any processed node ", referring to operation flow shown in Fig. 7 define scheme, can from " examine 6 " nodes are criticized to reject to " examination & approval 2 " node.It, can be with using the realization process for rejecting strategy in order to realize the application scenarios content Are as follows:

The next stage for obtaining the rejection node of operation flow description information executes node, and detecting next stage execution node is No is terminal node or end node, if so, terminating process；It is added to if not, the next stage of instantiation is executed node List to be adjusted, and as currently processed node, continue to detect its next stage execution node, until terminal node Or end node, finally, the state of each node in list to be adjusted is adjusted to rejection state, and the state that will reject node It is adjusted to state in processing.

As it can be seen that the present embodiment executes the rejection strategy, it can will examine 6 nodes and examine all nodes between 2 nodes The example state processing status that is updated to rejection state, and adjusts examination & approval 2 be " in processing ", regenerate 2 links of examination & approval It is pending to handle people, by this rejection mode of operation, realizes the unification of the example state to node each in orchestration instance It updates, ensure that the atomicity of operation.

For the exclusive or Xor node in orchestration instance, can circulate strategy execution according to exclusive or, such as to encounter Xor When type node, cleaning is using current XOR node to be all untreated pending in the source branch of terminal note；As process is gone to For node " exclusive or 1 " this operation flow description information, exclusive or used in this application circulation strategy is illustrated, that is, is realized The policy content of exclusive or process in the operation flow may include:

It is illustrated so that current exclusive or node is terminal node as an example, the closest branch node described using foregoing embodiments Matching strategy, the Look-ahead exclusive or node match branch node recently, and the nearest matching branch node found is to start to save Point, exclusive or node is terminal node, according to internode path traversal strategies given above, inquires between the two nodes and owns Path, the still untreated pending branch node of each branch node of forced termination, and node state is adjusted, it obtains next stage and executes section Point and automatic flow, wherein the processing status of orchestration instance interior joint usually may include initial value, in processing, located Reason and be rejected etc. four kinds of states.

For in orchestration instance implementation procedure, processing result is the node for not passing through or vetoing, the application is usually held Row can terminate policy map 7, specifically in such a case, it is possible to judge automatically whether entire orchestration instance can terminate, such as exist Operation flow shown in Fig. 7 defines in figure, and " audit 4 " node does not pass through, can be as follows for this application scenarios It realizes:

It is possible, firstly, to be obtained between start node and terminal node using above-described internode path traversal strategies All paths, secondly, that is, certain node serve is not tied in the path with the presence or absence of path is not terminated in the acquired path of judgement Beam is not carried out, if it does, process can not terminate, can maintain currently processed node, this is waited not terminate in path The corresponding services of each node finishes；If it does not, updating the example state of terminal node, and terminate process.

Join can be executed for the countersign type node in orchestration instance in conjunction with the description of the various embodiments described above Countersign circulation strategy, determines the circulation of countersign type node, specifically can judge automatically the industry when encountering countersign type node Whether business flow instance can circulate to next step, still by taking operation flow shown in Fig. 7 defines figure as an example, go to " countersign 2 " section Point, if can circulate to examination & approval 6, concrete processing procedure is as follows:

The nearest matched branch node (branch 1) for obtaining countersign node (countersign 2), inquires the branch node and countersign saves All paths between point, and obtain the countersign node upper level and examine the node passed through, in all paths inquired, mistake The path for the node that filter passes through comprising upper level examination & approval；It obtains in branch node next stage node (such as examination & approval 2, examination & approval 3) not The node of instantiation, then from remaining path, the path comprising the uninstantiated node is filtered out, judge last remaining road The last one in diameter executes whether branch node passes through, if passed through, the next stage node of the automatic flow countersign node, such as Fruit does not pass through, will wait in the countersign node, passes through until the last one executes branch node.

It is to be appreciated that during each branch process of operation flow, it can be real using the corresponding strategy such as the example above It is existing, but it is not limited to strategy described herein, it can be adjusted flexibly according to actual needs.

In conclusion determining currently processed node for countersign node or exclusive or node in operation flow implementation procedure In the case where, it can use closest branch node matching strategy, determine the nearest matching branch node of currently processed node, then time Go through this it is nearest matching branch node and currently processed node between path after, determine in these paths exist do not terminate path, It will be maintained at currently processed node, execute the corresponding service of each node not terminated in path；If not deposited in these paths not eventually Only path, updates the example state of currently processed node, and circulation to next stage executes node.
